Ramkumar Aiyengar commented on SOLR-6336: ----------------------------------------- I raised SOLR-6370 to catch such issues proactively. > DistributedQueue (and it's use in OCP) leaks ZK Watches > ------------------------------------------------------- > > Key: SOLR-6336 > URL: https://issues.apache.org/jira/browse/SOLR-6336 > Project: Solr > Issue Type: Bug > Components: SolrCloud > Reporter: Ramkumar Aiyengar > Assignee: Mark Miller > Fix For: 5.0, 4.10 > > > The current {{DistributedQueue}} implementation leaks ZK watches whenever it > finds children or times out on finding one. OCP uses this in its event loop > and can loop tight in some conditions (when exclusivity checks fail), leading > to lots of watches which get triggered together on the next event (could be a > while for some activities like shard splitting). > This gets exposed by SOLR-6261 which spawns a new thread for every parallel > watch event. -- This message was sent by Atlassian JIRA (v6.2#6252) --------------------------------------------------------------------- To unsubscribe, e-mail: dev-unsubscr...@lucene.apache.org For additional commands, e-mail: dev-h...@lucene.apache.org
